When you return to use the computer you find the screen has rotated! How do we return the screen to a normal view?
The issue may have been caused by leaving something on top of the keyboard, piece of malware or another person rotated the screen on purpose and did not return it to its normal position. You can easily fix this by holding the Ctrl and Alt keys down together. While they are pressed, tap on any one of the arrow keys, (located next to the number pad, or near the space bar on laptops), to rotate the screen to a desired position. Done.
